Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a surge killer component that combines a resistor and a capacitor in series, which absorbs a spark generated when a contact of an electromagnetic switch or the like is opened and closed.

[0002]

[Prior Art]

 In the past, surge suppressors that absorbed the sparks of the contacts of this type of electromagnetic switch had either fixed resistors and a single capacitor combined in series or mounted on one board to have two terminals. However, there was a problem that the installation area of was large.

[0003]

[Problems to be solved by the device]

 The present invention aims to provide a small-sized surge killer component having a structure having two terminals in a surge killer component in which a resistor and a capacitor are combined in series.

[0004]

[Means for Solving the Problems]

 Bend one lead wire of the fixed resistance element whose surface is coated with an insulating coating along the fixed resistance body side from the tip, and attach the bent lead wire to both sides of the organic film with a high dielectric constant inside the center. Connect the lead wire of the fixed resistor to the electrode inside the strip electrode of the capacitor film on which the strip electrode is formed by spot welding, etc., and spot the lead wire on the capacitor side at the end of the outer electrode in the same manner. Connected by welding, etc., the capacitor film is wrapped around the fixed resistor around the fixed resistor body to form an element, and a surge killer component with an electric circuit in which the resistor (R) and the capacitor (C) are arranged in series is formed. To do.

That is, according to the present invention, one lead wire of a fixed resistance whose surface is electrically insulated is bent from the tip to extend along the main body of the fixed resistance, and the inside of the capacitor film in which electrodes are provided on both sides of the bent lead wire. The surge killer component is characterized in that a capacitor film in which electrodes are connected and a lead terminal on the capacitor side is connected to an outer electrode of the capacitor film is wound around a fixed resistor main body to insulate the outer circumference.

[0006]

[Action]

 Compared to mounting individual fixed resistor and capacitor components on the board, respectively, one of the fixed resistor lead wires and one of the capacitor lead wires are shared, and there is no external connection and they are fixed. Since the resistor and the capacitor are in close contact with each other, the shape is further reduced, and a surge killer component in which a fixed resistor and a capacitor are connected in series with two terminals can be formed.
